7 Tips for Making Lightroom Run Faster

Not happy with Lightroom’s sluggish performance on your computer? Here’s a helpful 15-minute video in which photographer and instructor Anthony Morganti shares a number of helpful tips for optimizing your Lightroom’s performance.

The tips are various settings you can adjust and tools you can run inside Lightroom, from Catalog Settings to Preferences and more. Since photographers have different workflows and needs, customizing how Lightroom runs can help make it run faster for your own purposes.

Here’s a quick breakdown of the main performance optimization tips discussed in-depth in the video:

#1. Build 1:1 Previews: Make Lightroom create a 1:1 preview of your photo files, trading extra disk space and slower importing for faster performance while working with your photos.

#2: Discard Previews: Have Lightroom automatically discard your 1:1 previews after a certain number of days to free up disk space.

#3: Preview Size and Quality: Make sure your preview size and quality and set to appropriate settings for your monitor.

#4: Camera Raw Cache Settings: Increase your cache size as large as you can from the default of 1GB.

#5: Use Graphics Professor: Try enabling or disabling the use of your graphics processor to see if that improves performance.

#6: Smart Previews: You can give up disk space and editing quality by using Smart Previews for faster performance.

#7: Optimize Catalog: Use the built-in optimization tool to keep things humming along over time.

Watch the video at the top of the post for a more detailed look at how you can make these adjustments and what they can do for you.

The Sony a99 II is a Low Light Monster

Sony’s latest E-mount mirrorless cameras have wowed photographers with their low light and high ISO capabilities. Now it looks like its latest A-mount SLT, the new Sony a99 II, will do the same. Above is a 2-minute video showing its performance at ISOs up to 25600 in a room lit only by two candles.


“The sensor is spectacular, the level of detail is astonishing,” writes YouTuber bramansde, who posted the video. “High ISO […] essentially same or close of Sony A7Rii which uses the same sensor: when images are downscaled to 12MP, the noise at high ISO becomes equivalent to the A7s!”

bramansde also published a 10-minute video showing how the Sony a99 II performs at high ISOs in still photos by pixel peeping at some 100% crops:

They posted this sample ISO 102400 photo shot in “fine” JPEG with no noise reduction or post-processing:


You can find bramansde’s sample JPEG and RAW photos of the entire ISO range in this Google Drive folder.

The Sony a99 II is set to hit store shelves later this month with a price tag of $3,200. Main features include a 42MP full frame sensor, 4K video, a hybrid AF system, 12fps shooting, a 5-axis stabilizer, and 14-bit RAW.

$4,000 PC Destroys $4,000 iMac in Lightroom Performance Test, Report


It’s a sad fact for us Mac-lovers, but dollar for dollar, an Apple computer can’t keep up with a custom-built PC. And if you have any doubts about the veracity of that claim, a new report by the folks at SLR Lounge should put them to bed.

You can read the full specs of the computers tested as well as the detailed results here, but the long and short of it is this: the $4,431 27-inch iMac with Retina 5K Display was anywhere from 26% to 114% slower than their $4,370 custom-built PC at every single task tested… and they repeated each test multiple times to make sure they were being accurate.

The final verdict was easy to come to for SLR Lounge‘s Pye Jirsa. As he opines in the comments:

I think I was the most shocked by this comparison. I love Apple products and their designs (especially while Steve Jobs was around, I feel like they have gone down hill since then). But, I still just can’t justify the price to performance. I sat there re-running the tests multiple times just to make sure.

Nikon Test Shows the Blazing Speed of XQD Memory Cards Compared to CF

Nikon Asia just posted this performance test video showing how much faster XQD memory cards are than the CF cards they’re designed to replace (400MB/s versus 160MB/s). On a Nikon D4S DSLR, the XQD could record 67 uncompressed 16.2MP NEF RAW photos at 11 frames per second (or over 200 JPEGs in a single burst).

The faster speed also greatly cuts down the time it takes to transfer your shots to your computer. In the test, it took Nikon 1 minute and 55 seconds to transfer 1000 photos from a CF card to a computer. Those same 1000 photos were transferred in just 35 seconds using an XQD card — a 3x improvement.
